A/C System, Operating After Charging

WARNING: This page is about a different car, the 2007 Volkswagen Touareg, 2006 Volkswagen Touareg, 2005 Volkswagen Touareg, and 2004 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

If A/C compressor was removed, it must be cranked by hand at ribbed belt pulley/freewheel approximately 10 rotations before bringing into operation for the first time. This prevents damage in the A/C compressor due to liquid when switching the A/C system on. If there is oil in the A/C compressor cylinder, it will be forced out.

-- Start engine with compressor switched off (version with A/C clutch).
